[SOLVED] Connecting to PL2303 USB Serial Port with Moserial Terminal

Hi.
I have a USB to TTL Serial Port thing like in the photo below. And I want to connect to it from Moserial Terminal.

When I connect the device to a USB port and type lsusb I get this line for it. Bus 002 Device 004: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
And the device shows up as /dev/ttyUSB0 in Moserial Terminal under Port Setup > Device.

However when I click connect in Moserial I get Error: Could not open device: /dev/ttyUSB0

I am unsure if this is a permission issue where Moserial does not have permission to connect to the device, or a driver problem or something.

How do I proceed?
Thanks.
